Hi @flicka, I'm not sure if it helps you but another tool I use to find research type information is Google Scholar (https://scholar.google.com/). It has date links on the side so that you can select the newest articles and show patents and citations along with the search results. I did a search using the terms - methotrexate use with prednisone for PMR. Here are the results:

My first round with PMR took 3 years to get off of prednisone and the rheumatologist that diagnosed my PMR at Rochester Mayo Clinic had shared with me the story of one of his patients who was going back and forth between 1 mg and 1/2 mg dosage for a couple of years before he was able to get off with no pain. I don't know how long he had been diagnosed with PMR but I'm pretty sure if was longer than the 3 years I was struggling with at the time.
